Abstract
TiO2 nanotube arrays have attracted remarkable attention in recent years for diverse applications including water splitting photocatalysis, gas sensors, lithium-ion batteries and dye-sensitized solar cells, etc due to its semiconductor properties ,large surface area and nanotublar structures. Compared with TiO2 nanotube, free-standing and through-hole TiO2 nanotube membranes with optimized microstructure, direct electrons transfer,stability to mechanical vibrations,have a broader applied potential. This report presents several preparation methods of free-standing and through-hole nanotube membranes, and explains the mechanism of detachment process. These methods can be classified into two types: one is an in-situ method and the other is an ex-situ.
